The United States subprime mortgage crisis was like the storm clouds, not only the Dow Jones index downward trend, but also the Nikkei Index, the Hang Seng Index, at times under the influence of subprime mortgage crisis.For the US dollar keep on devaluating,whether the economic of United States and financial statement will be keeping in the same situation were becoming the heated discussion,and that cause more people think about the dollar standard status and the changing of international monetary system.

美国的次级债务危机犹如风暴云团，不仅令道琼斯指数持续跳水，日经指数、恒生指数也纷纷出现了暴跌行情，在次贷危机的影响下，美元一路贬值，对美国经济和美国财政长期是否可持续的担心，引起了更多人对美元地位和国际货币体系变局的思考。

ETFs are index funds at heart, so investors are encouraged to study the philosophy of index investing which downplays stock picking in favor of buying the market.

In 2003,the index of the landscape fragmentation has rised and the degree of the landscape fragmentation has changed seriously; the landscape of the soll and water loss has developed more and more multiple and fragmentized.

景观斑块个数增加，斑块平均面积出现不同程度的减少，景观斑块平均面积减少了5.7hm^2，景观破碎化指数1987年为0.914，2003年为0.922。破碎化指数增加，景观破碎程度加大。水土流失景观向多元化及破碎化方向发展。

The subject function values used nine indexes in tomato of high temperature stress including the rate of fruit setting, the relative output, the index of rolling leaves, the stabilization of membrane, the relative geminating of pollens, the contents of dissociating proline and the content of soluble sugar.

Antarctic sea-ice oscillation index with a seesaw pattern is defined Using NCEP/NCAR reanalysis girds data of monthly Antarctica sea-ice concentration from 1973 to 2002. The Relationships between the index of winter and the summer precipitations in China as well as the onset date of the summer East Asia monsoon are presented.

利用NCEP 1973-2002年逐月南极海冰密集度格点资料，定义了具有跷跷板式变化规律的南极海冰涛动指数，分析了冬季南极海冰涛动指数与我国夏季降水及东亚季风爆发时间的关系。

The results showed as:(1)Gegen decreases fasting insulin and insulin resistance index and increases insulin sensitive index of rats of insulin resistance induced by dexamethasone significantly;(2)Gegen can improve glucose tolerance of rats of insulin resistance but not to alloxan indued diabetes mice;(3)Gegen increases glucose intake of 3T3-L1 adipocytes and improves the insulin resistance of 3T3-L1 adipocytes induced by dexamethasone significantly;(4)Gegen can activate peroxisome proliferator- activated receptor gamma, make it bind to PPAR response elements;(5)Gegen can up-regulate mRNA expression of PPAR v ,aP2 and adiponectin.

结果表明：①葛根显著降低地塞米松诱导的胰岛素抵抗大鼠血清胰岛素水平和胰岛素抵抗指数，升高胰岛素敏感指数，改善大鼠的胰岛素抵抗；②葛根显著改善胰岛素抵抗大鼠的糖耐量，但对四氧嘧啶糖尿病小鼠的糖耐量没有明显的作用；③葛根显著增加胰岛素抵抗3T3-L1脂肪细胞对葡萄糖的摄取，改善地塞米松诱导的3T3-L1脂肪细胞的胰岛素抵抗；④葛根能促进HepG2肝癌细胞过氧化物酶体增殖物激活受体γ与靶基因的特异DNA序列结合，对PPARγ及其下游基因的转录具有激活作用；⑤葛根能够促进PPARγ及其下游基因脂肪酸结合蛋白(aP2)、脂联素mRNA的表达。

Rhizosphere bacteria community comparability index was decreased by MeSA, MeJA and third instars larvae of the maize stalk borer.

三种浓度的MeSA处理使根际细菌群落的相似性指数和多样性指数显著降低。

The results show that an internal and mutual transformation of land-use types cause striking changes in soil erosion extent. The transition of cultivated land to woodland and grassland medicates erosion intensity, and the one from forestland to cultivated land and grassland aggravates erosion. In addition, land-use practices, including mainly human activities, have impacts on the content of suspended sediment.

研究表明，本区土地利用类型的内部转化和相互转化引起土壤侵蚀程度的明显变化；耕地向林地、草地的转化使侵蚀强度指数显著降低；林地向耕地、草地转化，均显著增加侵蚀强度指数；耕地、林地、草地的内部转化对土壤侵蚀也有少量影响。

The interlayer oxidized zone and the concentration of uranium has the typical characters of low temperature geochemical processes. Interlayer oxidized zone can be defined from the bedrock to horizon C under hypergene weathering by such parameters as chemical metamorphosing、index of chemical weathering and index of mineral chemical differentiation.(2)Major elements can be divided into sensitive group、 active、 weak active and inert groups according to chemical metamorphosing parameter and fractional migration potential. For major elements of multivalent in the active group( Fe_2O_3、 FeO) and U, the migration and concentration trend in interlayer oxidized zone is apparent.

层间氧化带形成和铀富集成矿是地下水在低温、常压、开放体系、非平衡状态对围岩长期作用结果，元素含量及其有关地球化学参数在氧化带不同亚带中表现出一定的变化和分布规律，除Fe_2O_3、FeO、Fe_2O_3／FeO外其它元素含量及其参数只在统计学上呈现规律性变化，而不具分带意义，具有典型的低温地球化学作用特点；利用风化作用化学蚀变参数PC值、化学风化指数ICA和矿物化学分异指数ICV将层间氧化带作用界定于表生风化作用的基岩到母质层阶段。

The result showed that correlation coefficients of disease indexes between downy mildew and powdery mildew were 0.619 8 and 0.677 2 at the seedling and mature stages respectively, which were extremely significant. The correlation coefficients of downy mildew and powdery mildew for BC1P1 and F2 individuals from the cross between K8 and K18 were 0.492 5 and 0.493 3, and they were 0.497 6 and 0.286 8 for the cross of K10 with K18, respectively. These four coefficients were all extremely significant too. By AFLP analysis, E25M63-103 marker was linked to some susceptible quantitative gene controlling both downy mildew and powdery mildew. The finding proved further some resistant gene of downy and powdery mildews linked to each other from molecular level.
